Question 2

The Fourier transform of a signal h(t) is H(jω) = (2cosω)(sin2ω)/ω. The value of h(0) is

Question 3

The unilateral Laplace transform of a signal x(t) is

If x(t) be (e–at – ate–t) U(t) then value of a is

Question 4

Consider a system with U(t) as input and V(t) as output

Choose the correct option

Question 5

A continuous time signal x(t) = cosω0t is sampled with sampling interval Ts generating the discrete time sequence

If x(n) is periodic with period N and r is any positive integer, then Ts must satisfy the relation.

Question 6
